Do this from the order, not the Giftcards page:

1. Open the order under Checkouts that the gift card was purchased in.
2. On the gift card line, click Refund — it only appears while the order is not already fully refunded and the card is still Active (it disappears once the card has been Redeemed or already refunded/cancelled).
3. Confirm the "Are you sure?" prompt.

Sprwt immediately credits the buyer's digital wallet with the card's value (this refund always goes to the wallet, never back to the original card/payment method), marks the order as refunded for that amount, and sets the gift card's status to Cancelled — recording who refunded it and when, and linking the refund. The customer gets the "order_refund" email and your business gets an admin notification.

This is different from the Cancel Card button on the gift card's own admin page: that one only voids the card (sets it to Cancelled) and moves no money. Once a card has been redeemed by the recipient, Sprwt no longer offers a Refund button for it — you would need to handle that manually.
